Day 24 - Complete Jenkins CI/CD Project

Hello DevOps enthusiasts! If you conquered Day 24 of our Jenkins CI/CD series, great job! Today, dive into a hands-on Jenkins CI/CD project for your Node.js app. Build a sleek pipeline to streamline development and boost your resume.

Recap of Day 23 - Jenkins CI/CD Concepts:

Before delving into today's project, ensure you've completed Day 23 and grasped the fundamental concepts of Jenkins CI/CD. A solid understanding of the workflow and integration points is essential for implementing a robust CI/CD pipeline successfully. If you need a quick review, revisit the Day 23 materials to prepare for today's practical tasks.

Task 1: Forking Repository and GitHub Integration

Step 1: Fork the Repository

To initiate your Jenkins CI/CD project, begin by forking the provided repository on GitHub. This creates a personal copy under your GitHub account, allowing experimentation without affecting the original codebase.

Step 2: Connect Jenkins Job to GitHub Repository

Now that you have your forked repository, establish a connection between Jenkins and GitHub. Jenkins can automatically build and deploy your application when changes are pushed, streamlining development and ensuring seamless CI/CD pipeline triggers.

Step 3: GitHub WebHooks and CI/CD Setup

Take a moment to acquaint yourself with GitHub WebHooks, mechanisms that notify external services like Jenkins about repository events. Configure WebHooks for automatic CI/CD pipeline triggering with changes in your GitHub repository.

For a detailed guide, refer to the recommended video, providing a step-by-step walkthrough to solidify your understanding of GitHub integration and WebHooks in collaboration with Jenkins.

Task 2: Running the Application with Docker Compose

Step 1: Execute a Shell Script in Jenkins

In your Jenkins job configuration, set up an Execute Shell build step to run commands within the Jenkins environment. This step will execute your Node.js application using Docker Compose.

Step 2: Craft a Tailored Docker Compose File

Create a Docker Compose file customized for your Node.js application. Define services, networks, volumes, and configurations necessary for smooth operation in a Dockerized environment. Contribute to the open-source community by sharing your Docker Compose file.

If Docker Compose is new to you, explore the official documentation for insights into its structure and usage.

Step 3: Run the Project and Revel in Success

Once your Jenkins job is configured and your Docker Compose file is set, execute the job. Observe as Jenkins automates the build and deployment of your Node.js application through the defined CI/CD pipeline.

As the final step, treat yourself! Celebrate the successful implementation of your CI/CD pipeline and the deployment of your application. This accomplishment marks a significant milestone in your journey to master DevOps practices.

Conclusion:

With these tasks, you've taken a giant leap in integrating CI/CD into your Node.js development workflow. The synergy of Jenkins, GitHub, and Docker Compose not only automates your processes but also establishes a foundation for efficient and scalable software development.

Stay tuned for more exciting challenges and projects as you continue to elevate your DevOps skills. Happy coding and deploying! ??
